A SQL injection vulnerability in Z-BlogPHP 1.7.5 allows authenticated attackers to execute arbitrary SQL commands via the id parameter in the CommentBat feature.
AnalysisAI
SQL injection in Z-BlogPHP 1.7.5 enables authenticated low-privilege attackers to execute arbitrary SQL commands against the underlying database via the unsanitized id parameter in the CommentBat feature. Successful exploitation yields high-severity confidentiality and integrity impact - including extraction of password hashes, user data, and arbitrary record manipulation - with no availability impact indicated. No public exploit has been identified at time of analysis, and EPSS places exploitation probability at the 5th percentile, suggesting limited real-world exploitation activity despite the high CVSS score.
Technical ContextAI
Z-BlogPHP is an open-source PHP-based blogging and CMS platform maintained at github.com/zblogcn/zblogphp. CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) identifies the root cause: user-supplied input to the id parameter within the CommentBat batch comment management handler is interpolated directly into a SQL query without parameterization or proper escaping. This classic injection pattern allows attackers to append or modify SQL logic beyond the intended query scope. The CPE data provided in the intelligence record is listed as n/a, so product version scoping is derived solely from the CVE description (version 1.7.5). No database engine is specified, but PHP-based blog platforms of this class commonly use MySQL/MariaDB, where injection impact includes UNION-based data exfiltration and UPDATE/DELETE manipulation.
RemediationAI
No vendor-released patch has been identified at time of analysis - the supplied references point only to the upstream GitHub repository (https://github.com/zblogcn/zblogphp) and a researcher's CVE report (https://github.com/LING12138-sg/MyCVE-Report), neither of which confirms a patched release version. Monitor the Z-BlogPHP GitHub repository for a tagged release addressing this issue. As an immediate compensating control, restrict access to the CommentBat feature to trusted administrator-level accounts only, reducing the pool of users capable of reaching the vulnerable endpoint; note this may limit comment moderation workflows for lower-privilege roles. Disabling open user self-registration (if not operationally required) further reduces attacker ability to obtain the low-privilege account prerequisite for exploitation. At the code level, the id parameter in the CommentBat handler should be converted to a parameterized prepared statement - this is the definitive fix and carries no functional trade-offs.
